A place to raise pigs. The environment of pigsty mainly refers to the sanitary conditions such as temperature, humidity, gas and light that affect the environment, and is an important factor affecting the growth and development of pigs. Good environmental conditions can promote pigs to give full play to their growth potential In order to ensure the normal life and production of pigs and avoid the influence of rapid changes in external environmental conditions, it is necessary to artificially create microclimate conditions suitable for pigs' physiological needs.
The requirements of pigs for environmental temperature vary greatly due to different breeds, ages, weights and nutritional status. Generally, the optimum temperatures for newborn piglets are 32~34℃, 6 kg 24 ~ 27℃, 50 kg medium-sized pigs 20 ~ 23℃, large pigs 65,438+05 ~ 65,438+08℃, and boars 65,438+00 ~ 65,438+02.
Requirements of pigsty on environmental humidity;
Air humidity mainly affects pig production by affecting the regulation of body temperature. This effect is closely related to the ambient temperature. Whether it is low temperature or high temperature, high humidity is not conducive to the regulation of human heat. At the same ambient temperature, high humidity will lead to a significant increase in the incidence of pigs. On the one hand, high humidity reduces the resistance of pigs, on the other hand, parasites such as diarrhea, scabies, erysipelas and paratyphoid fever in piglets are easy to spread.
In pigsty, proper illumination is necessary for the normal physiological function of pigs. Proper light can make the pig's heat regulation function tend to be perfect, make the skin get exercise, promote skin metabolism, improve skin nutrition, at the same time enhance the body's metabolism and improve the body's disease resistance.
In addition, ultraviolet rays in the sun can also convert 7- dehydrocholesterol in the skin into VD to regulate the metabolism of Ca and P in the body, and ultraviolet rays have a strong bactericidal effect. However, too much light will destroy body tissues and cells and damage the skin. Strong light will lead to imbalance of heat balance, rising body temperature and heatstroke.
